TIMER."

Application flled May 5,

between the calm shaft-of an i engine. andv a timer arm is: effected; wearon: the: contact elements being? reduced: accordingly. An-; other object of r th ev invention? is: to provide novel means wherebythe casing .of-the timer may be adapted to receive: the oil 'rYVhlCh is disc'hargedi into' the'i crank: case: of" the ene gine, the timer being lubricated'by theoily fumesproceeding from the crank case; Another obj eet of the invention; is f to improve the :track and tlieiterminalsvwhich are traversed :by the roller: on the: timer arm.

lVith the above and 1 other objects in :view which will appear as the description-proc-eeds, the invention resides" in the combina; tion and arrangement' of parts and in the de+ tai-ls of constructionhereinafter: described and claimed, it beinglunderstoo'dthat, with-: in the scopefof what isc'laim'ed; changes in the precise embodiment of the" invention shown can be i made: without. departing from the spirit oi the I invention;

In the drawings:Fignre:1 shows 1 in ele-= vation, a device constructed: in accordance with the invention; Figure 2 is a sectionon the line2-2 of Figure 1 Figure '3is a: top plan; Figure 4 isa'section onthe line 14t of Figure Q'; Figure 51 is a section on. the line 5 5 of Figure 9-; Figure 6 is a section on the line 66of Figure 2.

The device comprises a support' including a pedestal 1 having a foot 2" provided with extensions 3 for securing the device in place on an engine, a cap 4 being held in one end of the foot 2 by any suitable means 5. A thrust bearing 25 is threaded into the low er end of the foot 2. The support includes a head 6 comprising a cup-shaped base 7 having a funnel'shaped bot-tom 8 carrying a sleeve 9 receiving the upper end of the pedestal 1, the bottom having a tubular outlet 10, a screen 11 being held in the base 7 above the outlet. The base 7 carries an arm 12 which aids in supporting the device. At its upper end, the base 7 is circumscribed by an 'oitset annular flange 14.

The head 6 includes a tubular upper'member 15 surrounding the base 7 and seated 1932? Serial: :No; 558,822;

removably in the fiangeu14,'.thek-narts;7 and 15 having ears16-whereuntcr thQLZGHdS'OT retractile springs 17 are connected zdeta-cl'iably the springswserving to hold ithe member: 15' onthe-base17. A bracketxl8; projectssfrom the upper member 15 andaids in support ingth-estructure The memberr15is prm vided adjacentzto itsupper-endwithnn ins wardly projecting. annular rib 19. Adid-QO is-hinged at 211to the-memberr15 of thc head 6 andihas a latch 22. adaptedatocooperate it the pedestal 1, a worm.27"beinglocatedin v the foot, and beingkeyed at 28: t0. the cam shaft 26. A timer shaft: 29' is ijournaledi in the pedestal-1: andhas -a collar 32 engaging the foot 2, the lower end of the shaft-2 being received in the thrust bearing '25,.theparts and 32 cooperating: to preventthe-shaft 29 from:mov-in-g endwise. A pinion 30 is keyed; at 31 tothe timer shaftz-29 andiis located in. the foot 2 the. pinion meshing with theworm 27 on the:cam:shaft 26..

An insulating. ring: 33 is located within the member 15 ELHdrIGStS-Olhthfi upper endrof the base. 7, the ring being L-shaped in cross section; An annular track 3 1, of insulating materiahis: supported onthe ring 33, the a track supporting an intermediateinsulating ring 35, which is T-shaped in crosssection, the-ring135 'carry-ing an annular insulating track. 36 supporting an insulating ring: 37, which is L-shaped in cross section, the ring 37 beingreceivedbenea-th the-rib-19=on the member 15, all-"of thezrings. and tracks-being bound! between the upper edge :of. theabase- 7 and the rib 19; An annular conducting member 38 is located between. the ring; 37 and the track 36 and is insulated by the ring 37 from the part 15. The conducting member 38 has depending terminals 39 seated in notches in the inner edge of the track 36.

An annular conducting member 40 is disposed between the track 36 and the ring and is spaced by the ring 35 from the member 15 of the head 6. The conducting member has upstanding terminals 11 which are seated in notchesin the inner edge of the track 36. An annular conductingmember 4-2 is disposed between the ring 35 and the track 3d and has depending terminals 43 seated in notches in the inner edge of the track 34. An annular conducting member 44 is located between the track 34 and the ring 33 and has upstanding terminals 45 seated in notches in the inner edge of the track 34. The conducting members 38, 40, 42 and 44 are provided with outwardly extended binding posts 47 passing through insulating plates 48 received in the openings 24 of the member 15 and extended downwardly behind the flange 14 on the base 7.

A nut 49 is threaded on the upper end of the timer shaft 29 and retains thereon a collar 50 having an outstanding finger 51. The device comprises a lever including an arm 53 having a socket 54 connected by pivot elements 55 with projections 56 extending from the collar 50. the numeral 57 marking a fork provided with a stem 58 held in the socket 54 of the lever, a roller contact 59 being journaled at 60 on the fork 57, the roller being adapted to traverse the tracks 34 and 36, and to engage with the contacts, or terminals, suehas the elements 45, for instance. One end of a retractile spring 61 is connected to the finger 51 on the shaft 29, the other end of the spring being connected to the arm 53 of the lever. The spring 61 maintains the roller 59 yieldingly in engagement with the tracks 34 and 36.

Especial attention is directed to the fact that, owing to the provision of the worm 27 on the cam shaft 26 and the pinion 30 on the timer shaft 29, the timer shaft rotates much more slowly than does the cam shaft. Likewise, the roller contact 59 moves with com parative slowness over the tracks 36 and 34, wear on the tracks being avoided accordingly. Any desired speed reduction may be brought about between the cam shaft 26 and the timer shaft 29, the number of conducting members 40, 42, 44 and 38 being determined accordingly, each contact member lnwing as many or as few of the terminals, such as the part 45, as may be expedient.

The oil may be introduced into the crank case of the engine through the head 6 and the outlet 10. The oily fumes, proceeding from the crank case, will enter the head 6 through the part 10 and will bring about a lubrication of those parts of the timer which are located within the head 6. If desired, a channel 100 may be formed in the upper end of the pedestal 1, the channel being adapted to hold a quantity of oil which will flow slowly into the pedestal, lubricating the shaft 29, the worm 27 and the pinion 30.

I claim:

1. In a device of the class described, a head comprising telescoped parts, a track within the head and bound between the parts of the head, spring means for connecting the parts of the head to cause them to hold the track, and a timer movable in the head and cooperating with the track.

2. In a device of the class described, a head, a track in the head and having seats in its inner edge, an insulating ring disposed approximately parallel to the track, an annular conductin member located between the ring and t e track and having angular terminals received in the seats of the track, the insulating ring comprising a flange located between the conducting member and the head, and timing mechanism cooperating with the track.

3. In a device of the class described, a support comprising a pedestal and a cupshaped head assembled with the pedestal, a shaft journaled in the pedestal, a track in the head, and a contact element carried by the shaft and cooperating with the track, the head being provided with means independent of the pedestal for receiving oily vapor from the crank case of an internal combustion engine and for conducting the oily vapor to the head, said means being so constructed as to transfer liquid oil from the head to the crank case of an internal combustion engine, the track being of annular form to facilitate the pouringxpf liquid oil into said means and into the ttom of the head.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.

JESUS M. LOPEZ.
